Body and mind. Mind and body. For all the Dance Central haters who've never actually played the game, the Xbox Marketplace has a demo available now to test out the hit title. Your body will thank you ... or cause you to retch from the exercise of a three minute dance routine.

As for your mind, beware the barbs of You Don't Know Jack emcee Cookie Masterson. The crazy quiz show also has a demo available today. And remember: Never give up, never surrender until the Jack Attack is over.
